2 Claims.

This invention relatesto roofs for railway cars and more particularly tothe roof construction and mechanism for securing the roof on the car.

One of the principal objects of the invention is the provision of a newand improved roof construction comprising a plurality of sheet metalplates having the carlines integral with the plates, together withreinforcing members for the carlines, the parts being so constructed andarranged as to form aroof that is cambered transversely of the car andthat is adequately reinforced when in position on the car.

Another object of the invention is the provision of new and improvedmeans forattaching a prefabricated roof structure in position on thelongitudinal and transverse framing members of a railway car.

A further object of the invention is the provision of a new and improvedcar roof construction built up from sheet metal plates and that iscomparatively inexpensive to fabricate, is light in weight and has amaximum resistance to stresses and distortion.

i Other and further objects and advantages of the invention willappearfrom the following devscription taken ,in connection with the accom- Ypanying drawings, in which Fig. 1 is a top ,plan view of acar embodyingthe invention, with parts. broken away and parts in section;

Figs. 8, 9, 10 and 11 are views similar to Fig. v6, but showing modifiedforms of the means for attaching the roof to the side plates and sideposts; and

Fig. 12 is a section on the line |2|2 of Fig. 1.

In the construction of the conventional railway car, the roof structureis built into the car as the structure is being fabricated. The roof inthe conventional type of car comprises roof sheet or sheets andVvcarlines that are Yseparate and are attached separately with theresult that the fabricated structure is heavy, contains a-n unnecessaryvamount of material and requires a considerable amount of time and laborin its construction.

The present invention seek-s to ysimplify the construction, lightentheWeight', strengthen the structure, and materially reduce the cost ofproducing the fabricated unit.

Referring now to the drawings, the reference character designatesgenerally a railway car having the under framing 2 supported by thetrucks 3, Figs. land 2, the side walls 4, end walls 5, flooring 6. androof section l.

In the construction of the car, the end and side walls, together withthe corresponding sills and side plates are fabricated separately onhorizontal sections by stretching the sheathing and welding together theframe and sheathing, after which these parts Vare assembled, as willpresently appear.

The side wall or outer sheathing ll'of the car comprises a plurality ofvertically extending strips or plates of sheet metal |3|,A see Figs. land 12, welded together inY such a manner that Vthe outer surface of theside Wall will be smooth. The side posts are made integralwith the sheetmetal strips, as shown more' clearly in Fig. 12. As shown, each sheet|3`| except the end sheets, has one edge'bent to Z-shape to form a sidepost 14|. The side post |4| 'is o-iset inwardly from the body of thesheet '|31 as at |38 to 'form a shallow recess for the reception lof thefree edge of the adjacent plate. The recess is of such a depth that-when the straight edge of the adjacent plate is welded in position inthe recess, the outer surfaces will be smooth or flush. The posts I4|are each preferably provided vwith a reinforcing angle lbar |42 which isnestedy in the inner angle of the side post and is welded thereto.

' The upper edge of the sheathing at each side of thecar, as well as theupper ends of the side posts MI, are rigidly attached to the innerr`side of the side plate |32, as by being welded thereto. The side plate|32 is angular, being roughly 4channel form with a downwardly extendingflange |35.

The'channel portion ofthe plate .faces .outwardly Y and is provided witha vertical'web portionl |60 and with .an outwardly extending upper.flange |36, as shown more clearly in Fig.{6r of the drawings. Y l n fThe top end plate 83 to which the end sheathing is attached is angularin cross section having the vertical portion |00, Fig. 7, the horizontalportion 95, seated on the end posts 8|, and an outwardly oiset verticalportion or flange I I. The upper edge is flanged outwardly as at ||0.Suitable gussets of any appropriate form are provided between'thevertical portion |00 and horizontal portion 95 of the end plate. In theform of the construction shown, gussets ||2 are preferably located abovethe intermediate end posts 8I. These gussets are U-shape in crosssection and are triangular in side elevation and have their basessubstantially the same width as the horizontal portion 95V of the endplate to which they are rigidly connected as by being welded thereto.The upper end or flange of the end plate extends horizontally over theupp er narrow end of the gusset plates and is welded Y thereto as shownin Fig. 7 of the drawings.

The roof construction comprises a plurality of carlines |62, Figs. 4 and7, and a roof member |63. The roof member |63 comprises a plurality ofsheet metal plates |64, Figs. 1, land 7, that extend transversely of thecar and are connected together in a manner similar to the plates formingthe outer sheathing at the sides of the car. In the form of theconstruction shown, however, these plates merely overlap, as shown inFig. 7. Except at the ends of the car, each plate |64 has one of itsside edges bent downwardly, as at |65, and flanged horizontally, as at300 to form inte-V gral carlines angular in cross section as shown inFig. 7. These roof sheets and integral carlines are so constructed that,when assembled, the roof isV cambered on its upper surface.

The depth of the vertical portion |65, Fig. 4, of each carline graduallydecreases toward vits ends to partially compensate for the cambering ofthe roof so that the under surfaces of the carlines will be more nearlyin a horizontal plane. YAs a result of this construction, the ilangeportion 300 of each carline will be considerably widened at its ends,`as indicated at |66 in Fig. 7. This widened portion may be partiallyremoved,

as shown in Fig. 7, or may be entirely removed, if.

desired.

The carlines are preferably reinforced by angle bars |61 which rest onthe ilanges 300 of the carlines and are rigidlyY connected to both thevertical and horizontal portions of the respective carlines. TheVcarlines are of such length that vthey are positioned between thevertical portions '|60, Fig. 6 of the side plates |32 and are rigidlyattached thereto as will presently appear. The sheets |64 extend overthe outer flange |36 of the side' plates A|32 as shown more clearly inFig. 6 Yof the drawings and are rigidly attached thereto. The carlinesare further secured to the vertical .portion |60, Fig. 6 of the sideplate by angle bars l|68 which extend across beneathrthe carline and theextension |66 as shown in Fig. 7 and are welded to the lower edge of thecarlines and to lwith the adjacent sheet in the same mannerY as thesheetV forming the side wall and integral side posts described above andshown in Fig. 12.

The front and rear ends of the roofV member l |63 are extended forwardlyand rearwardly over the upper flange I0 of the end plates 83 as shown"in lig.v 7, andare welded'thereto.

.bent inwardly beneath the carline SuitableV means are provided forrigidly attaching the side plate |32 to the side wall of the car. Asshown in Fig. 6, the upper edges of the, side walls or sheathing 4 ofthe car lap the inner surface ofthe depending ilange |35 of the sideplate and are welded thereto. In addition to this, the inner flange 2|4of the reinforcing member |42 is extended upwardly alongside the webportion |60 of the side plate |32 and is rigidly connected thereto as bybeing welded.

In Figs. 8, 9, 10 and 11 are shown modified forms of attaching the roofto the side plate.

In Fig. 8, the inner ilange 2|3 of the side Y post |4| is extendedupwardly alongside the web portion |60 of the side plate |32 and is thenbent inwardly to form a bracket for supporting the carline |62 and isrigidly connected to both 4 the carline and the web portion |60 as bybeing welded thereto.

In Fig. 9, the inner flange 2 |4 of the reinforcing member |42 isextendedupwardly along the web portion |60 of the side plate |32 andthen |62 and welded as in the previous construction.

, In Fig. 10, a separate bracket 2|5 is employed, the upper end of whichis bent inwardly to extend beneath the carline |62 and the body portionof which extends downwardly along the inner surface of the side plate|32 and downwardly along the inner surface of the side post |4| and iswelded to the carline,- the side plate and the side post for holding theparts in assembled relation.

In Fig. 1l, the inner flange 2|0 of the side post 4| is extendedupwardly along the inner face of the web portion |60 of the side plate|32 and is welded thereon. A separate bracket 2|6, bent to form anangle, has one flange beneath and secured to the carline |62 and itsdownwardly Yextending portion is in contact with the web portion |.60andwelded thereto.

Y This is a division of our application Serial No. 133,632 filed onMarch 29, 1937.

It is thought from the foregoing, v taken in .connection with theaccompanying drawings,

that the construction of ourdevice will be apparent to those skilled inthe art and. that changes in size, shape, proportion or details may bemade `without departing from the spirit and scope of .of the car andhaving the sheet metal extending over said flanges and rigidly connectedthereto, one flange ofeach of said side posts extending upwardly acrosssaid side plate and bent to Vextend beneath the adjacent carline andrigidly connected to said plate and carline.
